IMPROVEMENT IN 4liliAClINl POR GOATING HATS.

TO ALL WHOM'IT MAY CONCERN:

Be it known that we, JULES Fnnrvcors Marinas and Diisrn: MATHURIN Lncar,of Paris, France, have invented a new and improved Machine forManufacturing Sham Beaver Hats, and similar articles, and which we calla Pulvi-Feltering Machine; and we do hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming part of this specification,

This invention relates to a cert-ain machine for coating` hats orhat-frames with a powder of fur, wool, or other substance. The hat orframe to bc'coated is laid on an elastic support, and coated, powdered,and dried on both sides without its being necessary to lay hands on itssurface u ntil nished. We take a certain number of hat-frames previouslycoated withsome glutinous substance, place them on suitable frames, andsecure them to a shaft of peculiar form passing horizontally through aclosed chamber. This shaft rotates and recprocates, and thus imparts tothe framesa slow rotary mot-ion, and at the same time a rapid rocking orreciprocating motion, so that the inner and outer' surfaces of thehat-frames will be presented to the action of a strong continuouscurrent of foltering powder, in order to be, by a single operation,completely and appropriately coated. The continuous current of felteringpowder is produced by special fan, provided with screws, moving in theclosed chamber.

The annexed drawings, and a description of all the parts constitutingour machine, will make our invention better understood. Figure 1 is avertical longitudinal sectional view of our machine through :v fig. L

AFigure 2 is a cross-sectional view of the same.

Similar letters of reference indicate like parts.

A is a chamber in which are placed the hat-frames tov ber isitted withpanels, which will be hereinafter described, some of' which arestationary and others movable at will. The two extremeends of theframing are intended to hold the bearing and moving pieces. B is a fanfor exhausting the felteringpowder from' the lower part of the chamberA, in order to force it immediately towards the upper part, so as toform a strong endless current in the interior of said chamber. C arescrews with equal threads, but inversely inclined on the fan-shaft andeach `side of the wings, so as to bring the feltering powder from Vthelower part of the chamber A tothe inside of the fan-drum, placed partly'inside of the said chamber, and communicating therewith through the twoopenings formed laterally and opposite to the screws. D is'the shaft ofthe fan or ventilator and its screws. l E and E are pulleys fixed onsa'rdshaft D for receiving and imparting motions. F is the force-condnitof the fan, and G the swan-neck establishing communication between theconduit F and the chamber A, and terminates in a long slot, r, throughwhich cornes with great rapidity the feltering powder forced in by thefan. H is a horizontal and I a counter-shaft imparting, by means ofpinion M on I, and L on H, rotary motion to shaft H, and consequently tcthe hollow shaftfK, which carries the hat-holders. The shaft, KVsurrounds the shaft H, and is held concentrically with that shaft bymeans of springs R, which are secured to projectionsS on H, and S on K,and in such manner that the shaft K will rotate with the shaft I. i N isa spur-wheel, forming part of a sleeve, pb, which turns loose outheendof shaft H, being actuated by a pinion, O, on shaft d. P is a beatinggea-r formed of two toothed couplingboxes p andy', one of which, ip',formed with the spur-wheel N, is loose on the central shaft H, and theother, lo, moves only in a longi tudinal direction ou 'said shaft, sothat as theipart 1o is revolved, p will be thrown against the end oflche shaft K, and then moved back by a spring, Q,which continuallybrings thecoupling-box p /in contact with p. T represents one of threearms-affixed to the coupling-boxp of the beater P, so `as to communicatethe shocks of the i latter to the hollow shaft K in hitting theprojection t formed on the end of said hollow shaft. The intensity ofthe shocks may be regulated by compressing more or less the spring Q,between the end of shaft K and the coupling-box p of the beater. U arescrew-handles serving to fix the arms T-cn the coupling-box p, and tocause the central shaft to turn with the hollow one for more readilyfixing thereto or withdrawing therefrom the hats, all the straps beingon the locse'pulley's. V and V are pulleys xed on the countereshaft Ifor receiving and imparting motion. X and X' arepulleys fixed on thecounter-shaft T for receiving and imparting motion. Y

be coated. The framing forming the sides of the cham-l are supports forshafts I'and J. Z are flexible' three-branched supports, terminating infixed points for fixing thereto the hat-framesiand secured in loops ctfixed on the hollow shaft, as shown. b is a movable panel, forming adoor, hinged on its lower edge. c e are panels, that may be taken out tofacilitate access to the chamber. e-is a partition-valve, oscillatingaround its axis o for directing the current of feltering powder throughthe swan-neck conduit on the hats, or into the passagef, in order toexpel the powder from the chamber when the colors are to be changed,said valve bcingopened or closed by a rod, lr. At the end ot' thepassage f is hung a bag, which allows the air to pass through it, butretains the powder as'it is driven through the passage from the chamber.The openings formed in the partitions or panels for the passage of theshafts are provided with leather washers, rubbing against the shafts soas to prevent leakage.

I will now describe the'working of the machine.

The operator will fix the hat-bodies on the hollow shaft K byintroducing the lower paint of each support Z into the projections il,providedwith set-screws for that purpose. He will shut the door b-afterthrowing into the lower part of the chamber some handfuls of thefoltering powder of the desired hue to serve for the whole or part ofthe days work. He will bring the straps (moving on the loose pulleys) onthe fixed pulleys, and the operation of foltering is then going on. Theoperator then' brings down the straps on the loose pulleys in order tostop the movement of the machine. vHe opens the door b, undoes thescrews from the projections i, and withdraws the hats,- care being takento touch but the supports of the articles, which are then conveyedv tothe drying-room, from whence they are taken out for use. The hats may betransferred from the machine to the drying-room by being fixed throughsaid supportsvon a perforated rod, by means of which they are carried.One person is required to work the machine, and two more, either womenor boys, for coating the hats which are to feed it. The change of colorsis obtained 'by taking from ont the machine the felteririg powdercontained therein, and substituting another therefor. To remove thepowder -in* the machine it is necessary 'only to fasten a bag at the endof the passage f, and turn the valve to the position shown in red inlig. 1; then set the fan in operation, and the powder will be blownthrough the passage and into the bag. `It is only when the fan hasnothing more to expel that all things are set again in their originalstate, and that the feltered powder of the desired color is fed into thechamber. i

By this new process hats will be obtained of a notable finish, as thefoltering powder, `projected in a regular manner on their surface by astrong continuous current of air, will'impart to them a brightness andsuppleness which will, in our opinion, match the true and most genuinebeavers.

Having thus described our invention what we claim as new, and desire' tosecure by Letters Patent, is 1. A machine for feltering hats, made andoperating substantially as herein shown and described. '2. The hollowshaftK, combined and connecting with the sha-ft H by meansof springs RR, substantiallyas herein showa'd described.`

3. The beating apparatus P, in combina-tion with thespring Q,substantially as herein shown andpdescribed. 4. The arrangement of thevalve and passage or conduit f, in combination with the channel Fandface B, all made and operating substantially as herein shown anddescribed. I
